Salmonella contamination in a poultry-processing plant.
Bacteriological examination of 1,427 samples from a poultry-processing plant over a 2-year period yielded 202 (14.2%) cultures positive for salmonellae. The results indicate that contamination is reduced by washing procedures within the plant but that recontamination of the carcasses occurred in at least two different stages of processing, i.e., during evisceration and chilling. There was evide...
متن کاملCampylobacter contamination during poultry slaughter in Belgium.
The relation between internal carriage and surface contamination with thermophilic Campylobacter species in broilers was examined by molecular typing methods. Samples from 39 flocks were collected in three Belgian poultry slaughterhouses. From each flock, crop swabs before slaughter and intestines and neck skins during slaughter were collected. A total of 309 isolates were identified at species...
متن کاملCampylobacter contamination during broiler processing
Introduction The Campylobacter spp. are reported as the most common gastrointestinal bacterial pathogen in humans. According to the European Food Safety Authority (EFSA) report the number of cases in EU in 2005 was 197 363 (EFSA 2006). Comparing to 2004 a 7.8 % increase was observed. Poultry meat products are considered to be a major source of campylobacteriosis (EFSA 2005). The final product c...
متن کاملContamination of Poultry Products with Listeria monocytogenes at Poultry Processing Plants
This study aimed to confirm that poultry products packed at poultry processing plants have already been contaminated with Listeria monocytogenes and that poultry products contaminated with L. monocytogenes are derived from broiler flocks infected with L. monocytogenes. L. monocytogenes was isolated from 16.8% (58/345) of chicken breast products and 2.3% (8/345) of chicken liver products. In con...
متن کاملMathematical Frameworks for Modeling Listeria Cross-contamination in Food-processing Plants
The possibility of modeling the cross-contamination of Listeria species, total Listeria monocytogenes, or specific L. monocytogenes strains using a quantitative mathematical model using Monte Carlo simulation techniques is proposed. This article illustrates this approach using 2 different models: one that tracks L. monocytogenes number and prevalence for 4 different strains (Model I) and one th...
